An alternative approach for creating custom calculations in Tableau is using level of detail (LOD) expressions. LOD expressions allow you to perform calculations at different levels of granularity than the view, providing more control over the aggregation and the context of the calculation. They allow you to compute aggregations independent of the dimensions in the view, enabling intricate analysis and advanced calculations.

In addition to calculated fields, Tableau also provides table calculations that operate on aggregated data. Table calculations are powerful for computing running totals, percent of total, moving averages, and other analysis-specific calculations. Using the table calculation functions and addressing/partitioning options, you can customize the calculation behavior to suit your needs.

You can create custom calculations in Tableau using calculated fields. Calculated fields allow you to perform mathematical operations, string manipulations, and other transformations on your data. By writing formulas using Tableau's built-in functions and operators, you can create complex calculations that are not directly available in the UI.
